HILLER ATTACHMENT FOR CULTlvAToRs.

SPECIFICATION forming part of Letters Patent No. 768,029, dated August23, 1904.

` Application filed June l, 1903. Serial No. 159,474. (No model.)

To LZ2 whom, it may concern.-

Be it known that I, HIRAivrM. BURDroK, of

Utica, in the county of Oneida and State of` New York, have inventedcertain new and useful Improvements in Hiller Attachments forCultivators; and I do hereby declare that the following is a full,clear, and exact description ofv the invention, which will enable othersyskilled in the art to which it appertains to y attachment is adapted toefficiently perform 'ing-block employed in the attachment.

its work and is conveniently mounted on and removed from the machine andprovided with means for all necessary adjustments and is strong anddurable.

1n the drawings, Figure 1 shows a perspective view from the rear of awheel-cultivator with my improved hiller attachment applied thereto.`Fig. 2 shows one of the pair of hiller attachments, as seen from theinner side, in connection with a portion of the connecting-bars. Fig. 3shows the same as seen from the outer or nearly rear side. Fig. 11shows, on an enlarged scale, a part of the section taken on line A B ofFig. 3. Fig. 5 shows a horizontal section taken through the mount- Fig.6 shows an end or edge View of the mountingblock in connection with themechanism contiguous thereto.- Fig. 7 shows the same as that shown inFig. 6 from a different point ofV view.

Referring to the reference letters and figures lin a more particulardescription, A A indicate the gang-frames of the wlieel-cultivatorshown, which gang-frames are capable of being elevated or depressed andare also capable of adjustment toward and from the central line is .theattachment-head 7. `The attachmentlhead 7 is provided with an eyeoropening and a set-screw, and the branches of the U- shaped hangerare-inserted one in this eye andthe other in the opening in the piece 5and when adjusted to the proper position secured by the'said set-screws.The attachment-head 7'is provided with an upwardlyeXtendingAattachmentarm or post 8. The hiller shovel kor blade 9 is mounted on a shank 10,which extends upwardly at the side of they .attachment-head 7 and isattached 'thereto by a clamp and ratchet 11. The clamp and g ratchet areheld by the U-shaped clip 12, and

when loosened the shank 10 can -be adjusted vertically'and angularl'ywith reference to the attachment-head 7 When the nuts on the clip l2 aretightened, thebladeis rigidly secured to the head 7 vThe hilling shovelsor blades 9 are of an irregular form-that is to say, having a wingportion 9", which acts sub-` head are mounted vertically-adjustablesleeves 13, having set-Screws, by means of which they can be secured inadjusted position.

IExtending from the hiller attachment toA the hiller attachment on theother side of the machine are the connecting-bars 111 and 15. These barsat their ends are provided with a series of holes by means of which, inconnection with theV gang-adjusting mechanism on the frame, the distanceapart of the shovel attachments can be regulated. The connecting-bars 14and 15 are pivotally connected at each end to the sleeves 13, and thearrangement at this point is preferably as shown in detail in Fig.i-.-that is to say, an ear 13a on the sleeve is providedwith asomewhat-enlarged opening which receives the rounded portion of thepivot-piece 16. The piece 16 is provided with an' opening, and the endof the bar, j the piece 16, and the ear 13a are pivotally securedtogether by the bolt 17 passing through the three and provided withsuitable retaining-washers at eithervside.

It will be observed that by means of the construction shown and theseveral joints and attachments provided for that the hillerblades can beplaced at any desired angle with reference to the line of movement ofthe machine and at any desired angle with reference to the surface ofthe ground, and that the relation of the hiller attachment withreference to the gang and the working points of the gangteeth can benicely and carefully adjusted. When the attachment is used forcultivating a crop the plants of which have attained a considerableheight, the sleeves 13 can be adjusted more or less toward the top ofthe attachment-posts, and thus enable the connectingbars 14 and 15 topass over the top. In case the plants of the crop are not large thesleeves 13 will preferably be adjusted toward the foot of theattachment-posts, and thereby provide a more direct connection betweenthe hiller-blades. The two parallel connectingbars 14 and 15 serve toprevent any tendency of the hiller-blades to separate when at work,while still allowing a comparatively free vertical or oating movement.

What 'I claim as new, and desire to secure by Letters Patent, is

1. A hiller attachment for cultivators consisting of a pair ofhiller-blades, a shank on which said blades are severally mounted, anattachment-head to which the blade-Shanks are adjustably secured,hangers by means of which the attachment-head is secured to the rear endof the cultivator-gangs consisting of a U-shaped piece adjustablysecured in openings in the attachment-head and on the rear end of thegang-frame and a cross connection between the attachments mounted on therespective gangs, substantially as set forth.

2. A hiller attachment for wheel-culti Vaters consisting oi' a pair ofhiller-blades, attachment-heads on which the blades are adjustablymounted, U-shaped hangers having their branches adjustably secured invertical openings in the attachment-heads anden the rear portion of thecultivator-gangs, respectively, and a cross connection between thehiller attachments on either side of the machine consisting' of a pairof parallel bars pivotally attached to each device, substantially as setforth.

3. A hiller attachment for wheel-'cultivators consisting of a pair ofhiller-blades, attachment-heads on which said blades are adjustablymounted, hangers by means oi which said heads may be attached to therear portion of the cultivator-gangs, respectively, posts projectingupwardly from the attachment-heads, respectively, a cross connectionbetween the said `posts consisting of a pair ci parallel bars pivotallyattached at each end and means for adjusting said parallel barsvertically on said posts, substantially as set forth.

In witness whereof I have afiixed my signature, in presence of twowitnesses, this 25th day of May, 1903.
